Connect external hard drive to new MacBook Pro

I have an old Iomega external hard drive and used to connect it to my 2009 MacBook Pro via a FireWire 800 cable, obviously I can't connect it to the new MacBook Pro in the same way. Is there any way I can connect it to the new MacBook Pro with an adapter maybe?

You can with two dongles and it will be faster than USB 2. Get the Apple USB-C to TB2 adapter and the TB2 to FireWire 800 adapter.
Here is the supported interfaces of the USB-C to TB3 adapter: https://support.apple.com/en-us/HT207266
